It just occurred to me that there is a simple explanation for the recent cold weather, especially in the Midwest and East. Congress is not in session!
When Congress is in session, our representatives generate enough hot air to keep the jet stream up in Canada, thus keeping the polar vortex and its cousin, the Canadian clipper, where they belong.
But since Congress is not in session, there is not that counter-balancing hot air mass in place and here comes the cold air and weather.
This is probably the only time we should every wish that Congress was in session. Though I do wish they would do something meaningful when they do all that talking; but that is the subject of another blog.
